This paper explores signal response and methods for extracting the desired digital signal, from gas sensor arrays, while maintaining the shape and resolution of that signal. A comparative evaluation of Savitzky–Golay smoothing, moving average, local regression and robust local regression filters for cleaning signals obtained from gas sensor devices during the pre-processing phase is provided. It was found that the Savitzky–Golay smoothing filtering method provided the best approximation of the sensor response.
